com.sec.android.daemonapp | Difference Between Service and Daemon

What is com.sec.android.daemonapp, its purpose, and at the end, “how to fix com.sec.android.daemonapp has stopped.” Hello there! Welcome back to Gossipfunda. We will come to know about various terms which we have already heard, but don’t know any details about. We shall come to know about the formal definition of service, daemon, etc.

As society is getting modernized, its people are learning more and more about the backend kinds of stuff. For example, most of us use android devices. We don’t just use our device, we also tend to learn how the processes work. When you tap a button, how it redirects you to another place. We also tend to know more about the default built-in packages that android apps call while functioning. Hence, the technical terms are day by day getting clearer due to lots of free resources and documentation available. Gossipfunda is indeed one of the places with all useful technical articles like com.sec.phone.

Without any further delay, let’s begin this article. As mentioned earlier, we will be dealing with com.sec.android.daemonapp and going to know where it is used for. If you notice a lot of data usage by the weather apps, or the alarm clock of your device (which is suspicious), this is the app that you have to disable. So without any delay, let’s get started.

Difference between Service and Daemon

To begin with, we start with a very basic difference. You have heard the term service. A Service is typically is a piece of software that runs in the background on your OS. Services do not use “Graphical User Interface” or GUIs.

ServiceDaemon
Service is a program that responds to calls of other programs over some inter-process transmission tool, mainly overhead an interface. Service is whatever a server renders. daemon is a background application that runs freely without any interruption of a user, so also called a non-interactive program.

For example, let’s say you have started using a University Locations app. The app function is simple. It takes the name of any University from you and returns the location of that university. You then see that location in the app.

Let’s talk a bit about how this happens. The app, of course, won’t store the location data of all universities in the world on your device. That’s simply not possible because the size of the data may be several terabytes. All this data is stored in Google servers. When you ask for a location, the application does an API call through the Geocoder API. Google then returns the location data in form of a JSON (JavaScript Object Notation) file. The application’s code then parses the JSON file and shows you only the relevant data. This includes the university address, postal code, city name, state, and country.

So, this is a Service. Now through the Geocoder API, you can only make 2500 API calls per day for free. If you’re using it for some personal project then it’s fine, but at the enterprise level, you definitely need more calls. This is the reason why most of the applications ask you to go for Premium plans. A bound service persists until no more applications are bound to it.

Now, a daemon is a process that runs in the background without owning a Graphical User Interface either. Daemons and Services are inter-related, as services are daemons and daemons are typically considered services. They can be considered the same entity. The term “Service” is generally used to refer to the actions and APIs that the daemon offers. On the other hand, a daemon refers to only a piece of software.

What is com.sec.android.daemonapp

com.sec.android.daemonapp is the package for Unified Daemon, which is a system application in any of Samsung Android devices. Now that we know some information about what is a daemon, we can get back to our topic. So from its name, you know that it is some system package that contains various applications.

It is basically an application for showing News, weather, and Stock. The sites where it gathers the data and information from are Accuweather.com, Yahoo News, and Yahoo Finance. Some of the apps in your device that requests these data are Clock, Alarm, Camera, Briefing app, any weather app, etc.

So what happens is that, if you use the in-built Weather application or widget, it calls com.sec.android.daemonapp. The weather data is transferred to the weather widget and shown to you. It is updated frequently or seldom (as per you set it). If you set it to update frequently, then it’ll consume more data and the daemon will keep on running in background. This is not recommended. Hence by default, the weather is set to update every 3 hours.

The Unified Daemon app

The Unified Daemon app is built-in into your Samsung device. It provides support to numerous applications on your device, especially Weather, Yahoo News, and finance amongst others. In other words, any weather application needs to call this app for accessing weather data. Also, if you have Yahoo News or Yahoo Finance installed on your device, this is the app that is called. We are now going to see some common facts, and how to deal with them. When we are talking about fetching weather data, it requires internet usage. Let’s see how to control data usage by the Unified Daemon app.

How to stop or control the mobile data usage by Unified Daemon app?

As mentioned, data usage of the Unified Daemon app will depend upon the frequency of updating of the applications’ data. In case it consumes a lot of data, you can stop frequent updation of the apps by going to the app settings.  Lower its refresh rate and you’re done. Alternatively, you can set updation only over Wi-Fi, so that the apps refresh only when you are connected to the Wi-Fi. This is an efficient way to save data.

Follow these steps to achieve it:

  • Open Settings of your device.
  • Locate “Data Usage” and click on it.
  • You see the list of applications that consume the most of data. Scroll down and find “Unified Daemon” in the list. Note, that the list is sorted on the basis of data usage by apps and not by alphabetical order.
  • After you open the Data usage of Unified Daemon, tap on “Restrict Background Data.” Then, click OK.

This stops the app from running in background and use your mobile data to refresh apps. It updates by consuming data only when your device is connected to the Wi-Fi.

How to disable the Unified Daemon app?

Since this a system app, you cannot uninstall it. You need to have root access for that. Uninstalling is not required either. If its consuming a lot of data and unnecessary space, you may disable it by following the steps as mentioned:

  1. Open Settings of your Device.
  2. Then, locate and tap on Application Manager (or Apps, depends on your device).
  3. Go to “ALL APPS” section and locate and click on Unified Daemon.
  4. Click on “Disable”. In case any error message comes, like disabling the app may cause it to misbehave or crash, simply click OK.

So now you are done. You have successfully disabled the Unified Daemon app. However, the app will start running again when you open some other app which requires to call the Unified Daemon for some data.

How to fix “Unfortunately, com.sec.android.daemonapp has stopped”?

Now since this is a package, chances are that you’ll face this error. Facing these kinds of error is really annoying as the window keeps on popping up. This makes you unable to do any other task on your device. To fix this error, there are some common methods which you can try.

  • Head on to the “Settings” of your device.
  • Scroll down and go to “Applications”. If there are multiple tabs, then click on “ALL APPLICATIONS”.
  • Under that, locate the Unified Daemon app or alternatively, the package com.sec.android.daemonapp.
  • When the app page opens, click on “Force stop”. If you get a warning message saying if you force stop the app, it may misbehave, just click OK.
  • Now the error should get fixed. If not, click on “Clear Data”. This clears all data and cache for the app. The other option is to click on Disable and hence disable the app.
  • The ultimate option is to perform a factory reset, if you don’t have root access to uninstall the app. Factory resetting removes all the important data in your device. Hence, it is advised to take a backup of your data before you perform a factory reset. Factory resetting guarantees the solving of the problem because the bug causing the error is removed. However, for that, your device data is the cost.

Conclusion

So to conclude, com.sec.android.daemonapp is a built-in package found in Samsung devices. It deals with the inbuilt Unified Daemon app. The weather apps, Yahoo News, and Yahoo Finance are some of the apps that are supported by Unified Daemon. We have discussed how to restrict the usage of data by Unified Daemon in the background. So if you are facing heavy data usage by this app, you can follow the steps to stop that. Finally, we have discussed the traditional method of fixing “Unfortunately, com.sec.android.daemonapp has stopped”. Force stopping and clearing data or disabling the app is a solution, but if they don’t work, then Factory reset is the only option.
